Follow above operating procedures to confirm whether a regenerative resistor is needed or not. When the display changes
from
「
in00_-
」
to
「
in00_A
」
, the regenerative discharge is opened and the regenerative resistor is needed. For details, refer
to [Regenerative resistor]. Starting from low speed (20% of the highest speed), operating the motor to the expected movement
slowly and observing if the display value changes from
「
in00_-
」
to
「
in00_A
」
If
「
in00_A
」
displays, a regenerative resistor
is needed. Operation panel displays as follow:
Need a regenerative resistor Do not need any regenerative resistor
